2 Claims.

This invention relates to the treatment of wall surfaces to render the same water proof and pertains particularly to an improved preparation for accomplishing this result.

The primary object of the present invention is to provide a preparation which may be easily made up and applied to walls, particularly stuccoed walls to render the same impervious to moisture.

The present Water proofing preparation is not a coating for covering the wall surface to which it is applied but is absorbed by the same and coacts with the materials in the stucco to form an insoluble compound which will preserve the stucco by keeping moisture from being taken up thereby and causing the stucco to check and crack so as to provide means for the entrance of water into the interior thereof with the resulting deterioration of the stucco material and the rusting of the underlying supporting metal lath.

The present stucco water proofing preparation is made up of a water solution of the sodium salt of a fatty acid to which is added a hard fat such as suet or tallow, and a soft soap solution of a disinfectant, such for example as the disinfectant Lysol, which consists of a solution of cresols in a soft soap solution.

It is preferred that sodium stearate soap be employed in making up the present preparation. The preferred formula consists of a 5% solution of the sodium stearate soap, in water, to which is added 2% of melted suet. In order to incorporate the suet in the solution, the latter is heated to about 50 centigrade and the melted suet is then stirred in. There is then added to the soap and suet mixture, the Lysol or soft soap solution of cresols, in the proportion of approximately one tablespoon fluid oz.) of the Lysol to each two gallons of solution.

When this preparation is ready for use one part thereof is mixed with three parts of hot STUC- water and while it is still hot or warm it is applied to the wall surface to be treated, by spraying, pouring or brushing it on.

The application of this solution to stuccoed or plastered exterior or interior walls, or any walls that have a stucco Wash coat on them, will render the walls absolutely water proof, by the action of the stucco upon the solution which forms an insoluble compound which will preserve the stucco by keeping the moisture out of the same.

Since stucco is porous and absorbs moisture readily, the solution, which prevents this absorption, not only prevents the breaking down of the stucco through the action of the water thereon but also prevents the same from becoming dirty from dirty water which may come into contact therewith.

The preferred method of applying the solution is by spraying until the stucco is thoroughly saturated. The solution has no covering qualities and no coloring qualities.

It is only necessary to saturate the stucco with it to obtain the desired results.

Having thus described the invention, what is claimed is:-

1. The herein described method of making a water proofing solution for stuccoed walls, which consists in making a water solution of sodium tion.
